I took the car to my garage to diagnose the ticking noise when the accelerator is pressed. Get faster & louder as the revs get higher, more noticable when when in motion...

Now, the garage said it was a bolt that had broken off on the manifold and it would be about £200 to fix eeek. As he told me it would not damage the engine if it wasn't fixed i decided to leave it for a bit and put up with the noise.

Could someone explaine, if it is a nut that's broken, HOW does it get louder and faster the harder the gas peddle is pressed? also would it make a difference to the power of the car?

Cheers in advance chaps

Hi mate,

I take it that he was talking about a bolt that had broke on the Exhaust manifold, if so..........then it makes sense.

A blow in the manifold would cause a kind ticking noise........some mistake it for a mechanical issue.........more exhaust gases are released as the revs pick up- hence the blow from the manifold would get louder and louder as more gas escapes from the broken stud/bolt area faster.

This will affect performace mate and you may have problems when the MOT is due........I would get this fixed.

Super, cheers for the reply m8. Yeah think he was talking bout the exhaust manifold.
I thought £200 was a bit steep when he told me it was a bolt! Is this about right? Is there that much work involved to replace it?

If he said that the bolt/stud has snapped-off then thats bad dude...........theres not much room around there to begin with. If there is enough of the stud sticking out from the head- then you could get some extractors on it to remove it but if it has snapped futher in.........you're screwed.

When we get issues with broken studs or thread repairs- we use "Thread Doctor"- a specialist thread repair person/thingy- he comes out to sort it- this garage may actually call out a specialist to drill the stud out and then repair the thread- average charge for the "doctor's" services are around 100 squids plus vat and then of course the labour for taking the manifold off and then putting back on........200 squids sounds about right mate:thumbsup
